Definitions
- the invention relates to a method of ultrasonic shot blasting of parts which extend radially around the periphery of a wheel, such as blades turbine engine blades on a rotor.
- the invention also relates to a shot blasting machine for carrying out the process.
- wheel an object having a general form of revolution along a geometric axis, capable of being rotated around its axis.
- the angle of incidence is less than 45 ° relative to the perpendicular to the surface so that impacts can transmit energy sufficient of the ball to the impacted surface.
- Exposure of the part to shot blasting goes through an optimum. Insufficient shot blasting does not give resistance planned, but additional shot blasting can still be carried out. On the other hand excessive peening causes irreversible degradation of the part.
- the technique of shot peening applies in particular to compress the blades of the blades of a turbomachine rotor.
- microbeads activated by the vibrating surface strike the surfaces of the blades located in the active enclosure, on which they bounce, as well as the peripheral walls of the wheel located between the blades.
- Some microbeads come out of the enclosure active and are recovered in adjacent inactive enclosures from where they return to the bottom of the active enclosure by gravity.
- the thin ends of the blades are subjected to very strong impacts violent and they must be trimmed at the end of the blasting operation.
- the wheel turns on several towers. It is thus easier to reach the optimum, and to avoid asymmetries of shot blasting, generating deformation when the parts are thin.
- the object of the invention is to propose a shot peening process by ultrasound of parts which extend radially around the periphery of a wheel which allows effective shot blasting of the surfaces of these parts, whatever their length.
- the invention therefore relates to a method of ultrasonic shot blasting of parts which extend radially around the periphery of a wheel, method according to which we put the wheel in rotation around its geometric axis and we create a fog microbeads in a fixed active enclosure arranged laterally to said wheel, at by means of a first vibrating surface arranged in the lower part of said active enclosure having openings shaped to allow the input and output of the parts during the rotation of the wheel and being sized to accommodate at least three adjacent rooms.
- the method according to the invention is characterized in that one makes turn the wheel around its axis arranged substantially vertically and thereby that the first vibrating surface is arranged under the path of the parts in the active speaker.
- This arrangement makes it possible to impact all the surface areas of parts passing through the active enclosure regardless of their distance from the axis of rotation of the wheel.
- the enclosure has a second vibrating surface above the path of rooms in the active enclosure.
- microbeads which reach the part top of the enclosure with low kinetic energy and are ready to drop by gravity, are reactivated by this second vibrating surface, and participate in new to effective shot peening on workpiece surfaces and the walls of the active enclosure.
- This protection can preferably be provided by rods integral in rotation with the wheel and each masking a thin edge. These rods are arranged between the thin edges and the sonotrodes. They have the effect of decrease the energy of the balls likely to impact thin edges. They may be in contact with thin edges or slightly apart from them.
- It can also be provided by fixed rods integral with the enclosure.
- the wheel is rotated step by step during the blasting of in such a way that the edges of the parts located in the active enclosure are located in look of the fixed rods. Shot blasting can be stopped during pivoting one step away from the wheel.
- the rods are located between the edges thin blades and sonotrodes to protect the thin edges from impacts to high energy of the balls coming directly from a sonotrode.
- the invention also relates to a shot blasting machine for implement the method described above.
- the shot blasting device further comprises a second vibrating surface arranged in the active enclosure above the path pieces.
- the machine may also include means for protecting the edges of parts located opposite a vibrating surface.
- FIG. 1 a machine for shot blasting of the blades 2 which extend radially around the periphery of a wheel 3 turbomachine x-axis.
- the wheel 3 can for example be a bladed disc monobloc or a turbomachine wheel fitted with movable vanes.
- the blades 2 can also be parts whose surfaces must be blasted and which have means for retaining them radially and regularly spaced angularly at the periphery of a wheel 3 which then serves to support the parts to peened.
- the shot blasting machine 1 essentially comprises a plate turning 4 carried by a shaft 5 of axis 6 substantially vertical. Tree 5 can be driven in rotation about its axis 6 by drive means in rotation, an electric motor for example, not shown in the drawings. Wheel 3 is fixed on the turntable 4 by means of a clamping piece 7 cooperating with a threaded bore 7a of axis 6 formed in the turntable 4, such so that its x axis coincides with the axis 6 of the turntable 4.
- a first annular flange 8 is interposed between the turntable 4 and the wheel 3 and a second annular flange 9 is interposed between the wheel and the clamping piece 7.
- annular flanges 8 and 9 have rods at their periphery radial respectively 8a and 9a, in number equal to the number of blades 2 of the wheel 3, regularly spaced around the x axis. Each rod 8a and 9a takes up the forms trailing edges and leading edges of the blades 2.
- the annular flange lower 8 is positioned under the wheel 3 so that the beam of radial rods 8a covers the lower edges of the blades 2.
- the annular flange upper 9 is also angularly positioned relative to wheel 3 of such so that the rod bundle 9a covers the upper edges of the blades 2.
- the diameter of the turntable 4 is chosen according to the wheel 3 and in such a way that the blades 2 project radially outside the periphery of said turntable.
- the machine 1 further comprises a substantially horizontal fixed slide 10, integral with the support frame of the shaft 5, and whose axis is perpendicular to the axis 6 of the shaft 5.
- This shot blasting device 11 essentially comprises an enclosure so-called active center 12 disposed between two lateral enclosures 13 and 14 said inactive and intended to recover escaping microbeads 15 optionally from the center speaker and return them to the center speaker 12 as explained later in this memo.
- enclosures 12 and 13 and 14 are delimited together by a wall rigid external device 16 in the form of a circular sector and the diameter of which interior is substantially equal to or slightly greater than the diameter of the path traversed by the ends of the blades 2 during the rotation of the wheel 3 around axis 6, a bottom wall 17 in the form of a bowl which extends between the wall peripheral 16 and the periphery of the turntable 4 and an upper wall 18 in upside-down bowl or dome that extends between the peripheral wall 16 and the periphery of the upper flange 9.
- the lower wall 17 is arranged under the path traveled by the blades 2 during the rotation of the wheel 3 and the upper wall 18 is located above this path.
- a lower vibrating surface 20 is arranged in the bottom of the bowl formed by the bottom wall 17 is a second surface vibrator 21 is arranged in the upper part of the dome formed by the wall upper 18.
- the active enclosure 12 is thus delimited circumferentially by the partitions 22a and 22b and is arranged between the vibrating surfaces 20 and 21, as well as this is visible in Figure 5.
- This circumferential extent of this active enclosure 12 is such that at at least three blades 2 can be housed in this active enclosure 12.
- microbeads 15 A certain quantity of microbeads 15 is placed in the enclosure active 12.
- the microbeads 15 placed above the lower vibrating surface 20 are projected upwards, strike the surfaces of the blades 2, bounce on these surfaces and move on randomly.
- Some of these microbeads 15 reach the upper vibrating surface 21 which provides them with new kinetic energy.
- These balls 15 again strike the walls of the blades 2 during their descent. It goes without saying that certain microbeads 15 come strike the intermediate partitions 22a and 22b on which they rebound. These microbeads 15 remain in the active enclosure 12, and fall back onto the surface vibrant when they have lost their kinetic energy.
- microbeads 15 Due to the displacement of the blades 2 through the openings between the upper and lower intermediate partitions 22a and 22b, some microbeads 15 enter the lateral enclosures 13 and 14 through the space separating the contours of the partitions 22a and 22b of the nearest rods 8a and 9b. These 15 microbeads quickly lose kinetic energy in pregnant side 13 and 14, fall on the lower wall 17 which is inclined, and return on the lower vibrating surface 20 by the slots 23 formed at the foot of the lower intermediate partitions 22a and 22b.
- the blades 2 are impacted by the microbeads 15 for the duration of their passage in the active chamber 12.
- this passage time is clearly less than the total shot blasting time required to achieve the result optimum, and the number of turns to perform to obtain the optimum result is calculated accordingly.
- This number of turns is at least equal to 3. This allows reduce blade deformation resulting from temporary blasting deviations between the two sides of the blades during treatment. Indeed, when a blade enters in the enclosure, its face turned in the direction of rotation undergoes a blasting more intense than its opposite side because it is better exposed to high impact energy of the balls coming directly from the sonotrode. The prestressing of compression of the front-facing side is therefore greater than that of the opposite side, causing partially plastic deformation towards the back of the blade. When the blade comes out of the blasting chamber, it is the inverse phenomenon which occurs, but there remains however a deformation residual blade.
- N By blasting in N turns instead of one, the gap temporary peening between the two faces of the blades is divided by N, which substantially divides by N the resulting deformation of the blades.
- the number of turns It is not critical. Three to five turns is considered by the applicant to be acceptable to obtain a significant result.
- Figure 7 shows an alternative embodiment of the protection of the leading edges and trailing edges of the blades 2.
- the annular flanges 8 and 9 do not comprise beams of radial rods 8a, 9a.
- the protective rods 30 and 31 fixed relative to the device shot peening11, are mounted in the active enclosure 12.
- the number of rods 30 and 31 is equal to the number of blades 2 capable of accommodating in the active enclosure 12.
- the blades 2 are immobilized for a certain period of time in a position such as their leading edges and their trailing edges are protected by rods 30 and 31. Then they are displaced by a step equal to the angular difference between two consecutive blades 2.
- the rods 30, 31 are fixed by one end 32, 33 to the outer wall 16 and by the other end, to a common support 34, 35 which acts as a seal between the rotor 3 and respectively the interior walls 17, 18, this sealing being ensured when the clearances left are less than the diameter of the balls.
- This step-by-step movement is carried out at high speed if the shot peening continues during this movement, so that the leading edges and trailing edges are impacted infrequently when moving.
